      3. Viscoelastic acrylic foam core
      Exclusive to 3M, the acrylic foam core of 3M™ Acrylic Plus Tapes is engineered for stress relaxation when exposed to high stress loads, and conforms reliably even when the surface is curved or angled. It maintains consistent bondline aesthetics under normal stress loads. The inconspicuous black color of 3M tape PT1100T helps to ensure high satisfaction among consumers.

      4. Non-liner side adhesive
      Non-liner-side adhesive is excellent for bonding to automotive trim and other components.

      5. Clear T-liner
      T-liner prevents tape from sticking to uncoated side of 3M Branded liner.
